Geylang, or Geylang Serai, is Singapore’s red-light district. It lies east of the Central Area and the Singapore River. Geylang has been spared urban development and so has remained pretty much the same as has been since the 1970s.

Geylang is the only area where prostitution is legal in Singapore. The establishments that offer this service are easily identifiable as their house numbers are large and painted bright red.
